Christina Ricci's confirmed that the conspicuous rock she's been wearing since last fall is indeed an engagement ring.

A rep for the 32-year-old actress tells CNN that Ricci is set to tie the knot with beau James Heerdegen, a camera technician. He's worked on more than 40 projects, including CBS' new show "Elementary."

Heerdegen and Ricci met on the set of her now defunct ABC show "Pan Am," and Us Weekly reported the two were an item last February.
